1493802-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1493802-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,9,3,8,0 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1493802-20:
(9*1)+(8*4)+(7*9)+(6*3)+(5*8)+(4*0)+(3*2)+(2*2)+(1*0)=172
172 % 10 = 2
So 1493802-20-2 is a valid CAS Registry Number.

Direct amide formation from N-arylglycine ethyl esters and carboxylic acids catalysed by phenylboronic acid
Huang, Wenhua,Sha, Wen-Bin
, p. 460 - 463 (2013/09/12)
The phenylboronic acid-catalysed reaction of an N-arylglycine ethyl ester with various carboxylic acids, including N-acyl-N-phenylglycines, directly affords an amide or a dipeptide in 13-73% yields.
